DETAILED DESCRIPTION
[0019] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] like Figure 1 to Figure 4As shown, this embodiment proposes a small tractor heat-insulating top cover, including a top cover body 1. The top cover body 1 is a cylindrical structure. The top cover body 1 with a cylindrical structure can evenly distribute the load, so that the force is more evenly applied, and the cylindrical structure can better withstand external pressure and gravity load. A plurality of reinforcements 3 for increasing the strength of the top cover body 1 are also arranged on the top of the top cover body 1. Each reinforcement 3 is circumferentially arranged with the top cover body 1 as the axis. The cross-section of each reinforcement 3 is a semicircular structure. The semicircular cross-section has a higher moment of inertia and cross-sectional area, and can provide greater bending stiffness and load-bearing capacity. This enables the reinforcement 3 to effectively resist bending deformation caused by external loading and enhance the stability and safety of the structure. The top cover body 1 is provided with a mounting hole 5, an observation door 8 is provided inside the mounting hole 5, the observation door 8 is hinged with the top cover body 1, a heat insulation coating 4 for isolating heat is provided above the observation door 8, the heat insulation coating 4 is fixedly connected with the observation door 8, and the heat insulation coating 4 is preferably a ceramic coating, which usually has a high light reflectivity and can reflect solar radiation back, reduce the absorptivity of the substrate surface, and thus reduce the absorption of heat. The mounting hole 5 is provided to facilitate the installation of the observation door 8 and each insulation board 10 and each honeycomb board 9, and the observation door 8 is provided to facilitate the observation of the top of the top cover body 1. The honeycomb board 9 top cover body 1 is provided with a mounting groove 12, which is connected with the mounting hole 5, and a plurality of honeycomb boards 9 and a plurality of insulation boards 10 are provided inside the mounting groove 12. The cross-section of each honeycomb board 9 and the cross-section of each insulation board 10 are both fan-shaped structures, and the cross-sectional shape of the fan-shaped structure can provide a larger cross-sectional moment of inertia and bending stiffness, so that the honeycomb board 9 and the insulation board 10 can withstand a larger load and have better structural strength and stability. Through the mounting holes 5, each honeycomb panel 9 is placed into the interior of the mounting groove 12 to achieve a detachable connection. The same is true for each insulation board 10. The honeycomb panel 9 is made of polystyrene material. The thermal conductivity of polystyrene is low, so it has good thermal insulation performance. The insulation board 10 is made of polyurethane board. The polyurethane board has a very low thermal conductivity and can effectively isolate the conduction of heat. Its closed-cell foam structure can effectively prevent the convection of air and heat and provide excellent thermal insulation effect. An insulation groove 11 for reducing heat transfer is set below the mounting groove 12. A reflector 2 for reflecting sunlight is set on the top of the top cover body 1. The reflector 2 is fixedly connected to the top cover body 1. The reflector 2 is made of an aluminum-plated plate. The aluminum-plated plate is a metal plate with an aluminum layer plated on a substrate. The aluminum-plated plate has a high reflectivity and can effectively reflect sunlight and thermal radiation and reduce heat absorption.
[0021] A sunshade assembly for blocking the sun is also provided on the top cover body 1 in this embodiment. The sunshade assembly specifically includes a first telescopic rod 7, a second telescopic rod 13, and a sunshade cloth 6. The first telescopic rod 7 and the second telescopic rod 13 are both located at the bottom of the top cover body 1, and the first telescopic rod 7 and the second telescopic rod 13 are both fixedly connected to the top cover body 1. One end of the sunshade cloth 6 is fixedly connected to the first telescopic rod 7, and the other end of the sunshade cloth 6 is fixedly connected to the second telescopic rod 13. When shading is needed, the first telescopic rod 7 and the second telescopic rod 13 are pulled, and the sunshade cloth 6 moves with the first telescopic rod 7 and the second telescopic rod 13, and the sunshade cloth 6 moves downward. The sunshade cloth 6 blocks the rear of the tractor cab to reduce heat conduction.
[0022] Specifically, the implementation process of this embodiment is: install the first telescopic rod 7 and the second telescopic rod 13 on the top cover body 1. After completion, install each insulation board 10 into the installation groove 12 inside the top cover body 1. After the installation is completed, install each honeycomb panel 9 into the installation groove 12 inside the top cover body 1, fix the reflective plate 2 to the top of the top cover body 1, and spray the insulation coating 4 on the observation door 8.
[0023] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
